UNITED STATES PATENT OFFICE.

JOURNAL-B OX.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed February 6,1907. Serial No. 356,056.

To all whom it may concern:

Be it known that we, SAMUEL REYNOLDS and SAM- UEL J. REYNOLDS, citizensof the United States, residing at Plymouth, in the county of Luzerne andState of Pennsylvania, have invented a new and useful Journal-Box, ofwhich the following is a specification.

This invention relates to a car axle journal box of that general classconstituting the subject matter of the U. S. Letters Patent No. 717,452,granted to us on the thirtieth day of December, 1902.

The invention has for one of its objects to simplify and improve theconstruction of journal boxes of this character so as to be durable andsubstantial, comparatively easy and inexpensive to manufacture, andreliable in service.

Another object of the invention is to provide an improved lubricatingsystem whereby the car axle and bearing block are thoroughly lubricated.I

With these objects in view, and others, as will appear as thedescription proceeds, the invention comprises the various novel featuresof construction and arrangement of parts, which will be more fullydescribed hereinafter and set forth with particularity in the claimsappended hereto.

In the accompanying drawing, which illustrates one of the embodiments ofthe invention Figure 1 is a front elevation of the journal box. Fig. 2is a vertical section thereof. Fig. 3 is a central vertical sectiontaken at right angles to that of Fig. 2. Fig. l is a plan view of thebearing block.

Corresponding parts in the several figures are indicated throughout bysimilar characters of reference.

Referring to the drawings, 1 designates the body of the journal boxwhich comprises a casting or other metal structure composed of a flattop 2 provided with parallel upwardly extending flanges 3 and 4, thelatter of which is chambered to form a lubricant reservoir 5. Theunderside of the body is chambered to receive the journal of the caraxle and bearing block. This chamber is provided with a flat top wall (3and downwardly converging walls 7, so as to form a dovetailed groove,the said groove being open at the rear of the body and closed at thefront by transverse wall or abutment 8, Figs. 2 and 3. ln thisdovetailed portion of the chamber is confined the bearing block 9. Theblock is assembled through the rear open end of the dovetailed grooveand is prevented from working out by the wall or abutment S at the frontand the shoulder 10 of the axle collar at the rear, as indicated in Fig.3. Since the wall 8 is an integral part of the journal box body, thebearing block is positively held in place.

The walls 7 are undercut to form the oppositely disposed grooves 11,Fig. 2, for receiving the slide 12 of the journal box, which is providedwith longitudinal flanges 12 engaging in the said grooves. As shown 1 bydotted lines in Fig. 3, the grooves 11 terminate short of the rearsurface of the body 1, as indicated at 13, and the end walls of thegrooves form stops for engaging with the rear ends of the flanges 12.The front of the slide is closed by a vertical wall 14, so that acomparatively dust proof bearing is produced. On the front face of thebody 1 is a slotted lug 15 for receiving a cotter pin 16 that extendsover the front of the slide 12 to retain the latter in position. Shouldthis pin accidentally drop out and the slide 12 become detached, thejournal box will be practically unimpaired and the car will continue torun until a new slide is obtained to replace the lost one.

To supply the lubricant to the journal 17 of the axle, the bearing block9 1s provided with a plurality of inclined passages 18 adjacent eachend, and one pair of these passages is adapted to register with openings19 in the floor of the chamber or reservoir 5. The top surface of thebearing block is hollowed out in the form of two basins 20 that areconnected by a channel 21. By means of these basins and connectingchannel, lubricant can be fed to the axle through the passages 18alining with the openings 19 and also through the passages 18 at theopposite end of the bearing block, so that the axle journal isthoroughly lubricated at both ends. The passages 18 are symmetricallyarranged for the purpose of permitting the bearing block to bereversible. The chamber or reservoir 5 has a filling opening 22 which isclosed by a hinged cover 23 for excluding foreign matter. If desired, abody of waste may be employed in the chamber 5 to serve as a filter forpreventing grit from passing to the axle journal.

The journal box is attached to a car truck by presenting it to theunderside of one of the side beams of the latter with the flanges 3 and4 engaging, respectively, the rear and front faces of the beam. The top2 of the body 1 is provided with apertures 24 for the reception of thebolt that secures the box to the truck beam.

- What is claimed is A car axle journal box comprising a body having; alubricant reservoir and an axle receiving chamber, a bearing blockfitted in the chamber and provided with passages adjacent its ends andconnected basins on the top surface of the bearing block, and aremovable member on the body for closing the underside of the chamber,the bottom of the said reservoir being provided with openings forsupplying lubricant to the passages and basins of the bearing block. Intestimony that we claim the foregoing as our own, we have hereto affixedour signatures in the presence of two Witnesses.
